CIRCULAR-KNITTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 779,423, dated January10, 1905.

Application filed October 31, 1902. Serial No. 129,521.

T all whom it may concern:

Be it known that I, HARRY A. HoUsnMAN, a citizen of the United States,residing at Philadelphia, county of Philadelphia, and State ofPennsylvania, have invented a new and useful Improvement inCircular-Knitting Machines, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,which form a part of this specification.

The object of my invention is an improved circular knitting machinewhich will automatically and without stoppage of the machine produce aseamless stocking having a I 5 lace or tuck stitch upon the front of theleg, the instep, and upper portion of the stocking, tuck stitch workupon the rear of the leg, and plain stitches upon the heel, toe, andsole of the foot.

2 In a previous patent issued to me, No. 654,347, dated July 24-, 1900,I have shown, described, and claimed devices so combined in acircular-knitting machine that tuckwork is formed in a seamless stockingupon certain 5 of the needles used to form the front of the leg, theinstep, and the top of the foot.

In my present invention I provide, in addition to the above, separatemechanism that will form tuck-stitches upon certain needles 3 used toform the back of the leg of the stocking. The last-mentioned mechanismis automatically and in the operation of the machine thrown out ofaction during the formation of the heel, toe, and sole, while during theformation of the leg the two tuck-stitch mechanisms operate in unisonand uniformly. A circularknitting machine embodying my improvements willknit a stocking such, for instance, as is shown and described in Letters4 Patent of the United States No. 702,843 in the continuous operation ofthe machine.

For the general construction of the circular-knitting machine to whichmy improvements have been added reference may be had to Letters PatentNo. 538,518, issued to me April 30, 1895.

In the drawings, Figure 1 is a side elevation of a part of my improvedknitting-machine. Fig. 2 is a side elevation of the operating-cam andits driving mechanism. Fig. 3 5 is a plan view of the same. Fig. 4: is aplan view of pattern-plates. Fig. 5 is a side elevation of the machine.Fig. 6 is a section through a portion of the cylinder, showing theoperating-levers and their connections. Fig. 7 is an enlarged sideelevation of portion of machine. Fig. 8 is a top plan view of machinewith thread-guide omitted, showing the action of lever 16, dotted linesshowing position of parts before action and full lines while in action.Fig. 9 is a view similar to Fig. 8, with lever 13 in action.

Fig. 12 is a detail perspective viewof block 3. Fig. 13 is an elevation of the interior of the cam-cylinder.Fig. 1A is an elevation showing the levers 13 and 16. Fig. 13 is an en-7 larged view showing a portion of the wall of the cam-cylinder with itscut-away portion and tongue and the block 3 resting therein. Fig.

15 is a diagrammatic View showing the action of the switch or needle camwhen in its high position upon the long and short latched needles. Fig.16 is a similar view with the needle or switch cam in its low position.

' The machine of Patent No. 538,518, as is Well known, consists of anoperating-cam cylinder A, which is driven by the gear B upon the shaftZ), which shaft 7) is rotated by means of the bevel-gear c on thedriving-shaft D, meshing with the gear 0 loose upon the shaft 5andreciprocated by means of the gear D, 8 5 also loose upon the shaft 5,operated by the rack D By means of the clutch D feathered upon the shaft6, the shaft 6 is connected with either the rotary gear 0 orreciprocating gear D, and thus the cam-cylinder rotated or reciprocated.The needles are held in levers E and E The levers E control thoseneedles which in the manufacture of circular goods, such as stockings,are during the formation of the heel and toe thrown out of action. Inthe operation of this machine, as is fully set out in the Patent No.538,518, last mentioned, before the levers E are at the desired point inthe knitting they are automatically oper ated upon to throw them out ofaction bya plate F, in which the tails of the levers E rest, the platehaving depending rodsf, which are operated upon by mechanism describedin said patent to move the rods and plate. In order to operate upon thedesired number of levers E and their corresponding needles to throwcertain of the needles in and out of action for predetermined rotationof the camcylinder, and thus form the tuck-stitch, I add the followingmechanism to this part of the machine:

I make my levers E with bifurcated ends a c. The plate F is formed witha cut-away portion f, beveled at its lower surface f in which the endrests. Upon the top of this plate F is a pattern-platef, removablysecured thereto and which projects into the space between the ends 0 eof levers E. In this plate f corresponding to the levers desired to beacted upon in the formation of the open or lace work of the fabric, areorifices f of a size sufiicient to allow the tail 6 of lever E to passup through them. For the rods f, connected to the plate F, I use tubes.Superimposed upon the pattern-plate f 3 is a second pattern-plate fremovably secured to the plate F. The plate F has a cut-away portion inwhich the end a of lever E rests. The pattern-plate f has a portionwhich projects into the space between the ends 0 e of the levers E, andthe thickness of the plates f f is equal to the space between said ends.

The upper surface of this plate f is beveled. In this pattern-plate fcorresponding to the levers which are not desired to be acted upon inthe formation of the open or lace work of the fabric, are cut-awayportions f of a size sufficient to allow the tails e of the levers E topass through. Secured to the plate F by nuts f" are the rods f and f",which pass through orilices in the patternplates f and f and plate F andthrough the tubes f. The lower end of rod f passes into an orifice g inthe lever Gr, and by means of a nut g the vertical height of the rod fmay be adjusted. This lever G is secured to the rock-shaft G. The lowerend of rod f 9 is correspondingly secured to a lever G which is alsosecured to the rock-shaft Gr. The end of lever G opposite the shaft Ghas upon it the cam-plate Upon the rods f 7 and f are the springs f H isa lever pivoted to the frame of the machine at it and having at one endthe camplate It, adapted to operate the camplate g When the lever Grisin the position shown in Fig. 1, the rods f f" are lowered and theneedles acted on by the plate F are in action. When the plate F is movedto the position shown in Fig. 6, the cam-plate operates on the cam-plateand through it upon the lever G, lifting the rods f f" and elevatingplate F and certain of the needle-levers E, throwing those needle-leversand their needles out of action. I operate this lever H as follows: j j"are pins upon the lever H below the pivotpoint h. J is a superposedplate having a roller J at its lower end and slots j j through which thepins jj project. K K are two cams secured upon the face of thegear-wheel K. The cam K projects from the face of the gear-wheel agreater distance than does cam K The roller J is normally in suchposition that it rests against the cam K at a point above the cam K Thecam K is so formed that in the revolution of the wheel it maintains thelever H in the position shown in Fig. 1 or returns it to that position.In order to bring the roller J under the influence of both cams K and Kand remove it from such influence, I provide the following mechanism: Zis aprojection from plate J, which by means of link Z is connected tobell crank lever L, one arm of which has at its end the toepiece Z andbelow the end the pin Z to which is connected a spring Z", whichnormally holds the bell-crank L and the plate J in the position shown inFig. l in contact only with the cam K. In this position the toe-piece Zis in line with a pattern-chain M upon the shaft on. Upon this chain isthe lug lV This lug in its movement strikes the toe-piece Z moving thebell-crank L against the action of the spring Z, depressing the plate Jand bringing the roller J into operative relation with both cams K and Kat different portions of the gearwheel K.

In the specific illustration shown in the drawings the gear-wheel K isintended to make one revolution for three revolutions of thecam-cylinder, and, as shown, the cam K controls during one-third of therevolution and the cam K" during two-thirds of the revolution when bothare acting. Thus when the bellcrank has been acted on by the lug on thepattern-chain, as just described, the lever H will be acted on to throwthe predetermined needles out of action for two revolutions of thecamcylinder and in action for one revolution. The lever L is locked inits position after action upon it by the lug M on the pattern-chain byreason of the pivoted latch N, which by gravity engages the pin Z". Thelatch N is released and the bell-crank L returned to its initialposition by the projection N on the pattern-chain M, which strikes thelatch N, lifting it, and the spring Z draws the bell-crank L to itsinitial position, lifting the plate J, bringing the roller J into actiononly with the cam K, and the cam K will operate the lever H and theplate F to bring the levers E into action. The position of the cam Kwith reference to the gear K is such as to make it operative, so thatthe needles will be thrown into action at the proper time. WVith mymechanism in order to arrange which of the needles are to be thrown inand out of action during the formation of the lace or open work it isonly necessary to arrange the pattern-plates f and f that is, provideorifices in the plate f corresponding to the tails of the levers Edesired to be thus operated and orifices in the plate f corresponding tothe tails of the levers E not desired to be then operated. By having aseries of these plates with orifices at different points change ofpattern may be obtained by merely changing the patternplates. While Ihave described the cams K and K as being such that in one revolutionthereof the cam K acts through two-thirds of the revolution and the camK one-third and that they are designed to run as one revolution forthree revolutions of the cam-cylinder, this may be varied, as it may bedesirable to have the needle stitch every second course or only everyfourth course, and this would only require a change of extent ofrotation and relative revolution of the cams.

The preceding description relates to that part ofthe machine which isused to form the lacework upon the front of the stocking and with theneedles which are thrown out of action during the formation of the heeland toe and which is disclosed in Patent No. 654,347. I will nowdescribe the additional features over those of the last-mentioned patentand which form the subject-matter of the present invention. Theparticular object of these additional features or devices is to providetuck-stitching upon certain fashioning-needles Z Z during the formationof leg of the stocking, and thus form a tuck-stitch all around the legof the stocking and yet have no tuckstitching upon these needles duringthe formation of the heel, toe, and sole. Further, I so connect thetuck-stitching mechanism of these fashioning-needles with thetuck-stitching mechanism of the non-fashioning needles, beforedescribed, that when the tuck-stitching mechanism of thefashioning-needles is in operation the tuck-stitching will be uniformthroughout. The fashioning-needles,as is well known, incircular-knitting machines are those needles which are used to form theback of the stocking, the heel, toe, and sole. They are termedfashioning-needles because in the formation of the heel and toe theirnumber is gradually reduced course by course until the fabric isnarrowed down and then gradually increased course by course until thefull number are again in use. This is called fashioning, and the needlesused in this operation are termed fashioning-needles. They compriseone-half of the needles and arein practice placed in the front half ofthe machine. Speaking generally, the tuck-stitching upon thefashioning-needles is accomplished in the following manner: Such of thefashioning-needles which I intend to use to form tuck-stitches I formwith latches of extra length, so that in the normal position of suchneedles the regular throw-01f cam of the machine will not in itsordinary position lift the needles high enough to throw off the stitch.These'needles are lettered Z. I also arrange this throw-0E cam so thatit can be elevated to such a level that these tuck-stitchfashioning-needles, as well as the remaining fashioning-needles, will beelevated high enough to throw off the stitch. Thus it may be seen thatwith the throw-off cam in its normal position the fashioning tuck-stitchneedles will receive but not cast off a stitch. I also provide mechanismor devices for lifting the regular throw-off cam to a level or heightthat will throw off the stitches upon the fashioning tuck-stitchneedles. I also connect the mechanism for lifting this throw-off cam sothat it is lifted during rotary work of the machine during the samecourse that the mechanism to 01)- erate the non-fashioning tuck-stitchneedles to throw off their stitches acts. I also provide mechanism whichwill operate the camlifting mechanism so that the cam is elevated andmaintained elevated during reciprocating work of the machine (formingthe-heel and toe) and during the formation of the sole.

I will now describe the specific mechanism illustrated in the drawingsfor accomplishing the above purposes. The wall of the camcylinder A iscut away, forming the slot having the projecting tongues 2. In this slotrests the block 3, having the vertical slots I, in which rest thetongues 2. Between the top of the block 3 and the under surface of thetop of the cam-cylinder is the spring 5, tending to hold the block atits lower point. The block has the projecting cam-face 6, which projectsoutwardly beyond the cam-cylinder.

The stitch-cams of my machine, speaking generally, are shown in LettersPatent No. 521,860, dated June 26, 1894, granted to me. As shown in thatpatent and in the drawings illustrating my present invention, I use as apart of the stitch-cams the switch-cams 7, each of which normally restsagainst a corresponding stitch-cam 12. As in my previous patentmentioned, each of these switch-cams 7 has a pin 8 secured to it, whichpin rests in an orifice 8 in the cam-cylinder, and a springactuated pin8 bears against said pin 8. The function of these switch-cams 7 of thestitchcams is in ordinary knitting both reciprocation and rotation todetermine the direction of the travel of the needle, whether above orbelow the stitch-cam 12. Its operation is clearly described in myprevious patent spoken of and may be stated here as follows: Themovement of the cam-cylinder causes a switchcam 7 to strike a needle. Ifit is the upper surface of this switch-cam which strikes the needle, theneedle follows that surface toward the top of the stitch-cam 12. If itis the under surface of the switch-cam 7 which strikes, the needle liftsthe switch-cam at that point, allowing the needle to pass. In thepresent machine the function of these switch-cams, so

far as the purpose heretofore described is concerned, is the same as inthe previous patent mentioned.

In my improved construction in addition to the above one of theswitch-camsas shown, the left-hand switchcamis provided at or near oneend with a pin 10, which rests in a horizontal slot 11 in the block 3,so that While still connected as in my Patent No. 521,860 its uppersurface will by the vertical movement of the block be elevated ordepressed 0., is vertically movable. hen at its lower position, itsheight is such that in the passage of the needles over it beforereaching the stitch-cams 12 the long-latched needles are not elevatedsufficiently to throw off the stitch, while the short-latched needlesare elevated sufficiently to throw off their stitches. (See Fig. 16.)When the block is elevated, the upper surface of the cam 7 is elevatedsufficiently to lift both the long and short latched nee)dles, so as torelease the stitch. (See Fig. 15.

13 is a lever or plate pivoted at 14 upon a plate 17, secured to thecam-cylinder, and having the projection 15, adapted when the lever 13 isswung to move under and operate upon the cam-face 6 of the block 3 andlift the block. This lever or plate 13 has also the projecting portion15. The plate or lever 13 is also pivoted at 13 to a second plate orlever 16, which latter lover is also pivoted at 16 to the plate 17; butthe plate or lever 13 is at a higher level than the plate or lever 16.The plate or lever 16 has also a projecting portion 18. Secured looselyupon, so as to be movable around the upright 19, is the arm 20, held infrictional contact therewith by the pin 20. The outer end of this arm isprovided with the cam-face or operating-cam 21.

22 is a frame secured to the upright 23 and loosely surrounding theupright 19. In a projection 24 from frame 22 is the set-screw 25, and aspring 26 connects the arm 20 and frame 22. By lifting either upright 19or 23 the arm 20 is lifted. hen it is lifted, the camface 21 is in linewith the projecting portion 15 of the lever 13 and in the rotation ofthe canrcylinder is acted on to lift the block 3 and the cam 7 to aposition to throw off the stitch on both the long and short latchedfashioning-needles. When the uprights 19 and 23 are down, the cam-face21 is in line with the projection 18 .of lever 16, which by the previousaction has been moved into such alinement, and in the rotation of thecam-cylinder moves said lever and through it the lever 13, releasing theblock 3, which by the action of its spring returns to its low position,bringing the switch-cam 7 to the low position, where only theshort-latched needles of the fashioning-needles cast their stitch. (SeeFigs. 8 and 9.) The upright 19 is supported and guided so as to bemovable and is provided with the spring 27, tending to hold it in itslower position. The end of this upright 19 rests upon one end of thepivoted frame 28, the other end of the frame 28 being connected to aconnecting-rod 29, which in turn is connected to the crank 29 upon theshaft G. The upright 23 is also guided so as to have avertical movement.The lower end of this upright has the collar 30, which is provided withthe projection'31, under which one end 32 of the pivoted gravity dog orcatch 33 is adapted to rest. This dog or catch 33 has the cut-awayportion 34.

36 is the frame to which the shifting-rods 37 for the clutch D areconnected. This frame 36 is connected to the upright 38, operated by theclutch-shifting cam 39 and frame 46, all as in Patent No. 538,518,heretofore referred to, and for shifting the clutch to change theconnection of the cam-cylinder from rotation to reciprocation.Projecting from and connected to the frame 36 is arm 41, having at itsupper end the lateral projection 42 and the vertical projection 43. Uponthe lower end of the upright 23 is the projection 44, having thetailpiece 45. The cutaway portion 34 of the catch 33 is in line ofmovement of projection 43 and the projection 44 in line of movement oflateral projection 42. The pattern-chain M has also upon it the lug 50.The revolution of pattern-chain is so timed and the lug 50 so arrangedupon it that the lug strikes the tailpiece 45 at the time the body ofthe foot is being formed.

' From the foregoing the operation of the machine may be'readilyunderstood. WVhen the leg of the stocking is started to be formed, theuprights 19 and 23 are both down (see Fig. 7) and the lever 13 free fromthe block 3 and the switch-cam down, so that the long-latchedfashioning-needles will not lose their stitch. During the rotation ofthe cylinder forming the leg at each time the rock-shaft G is operatedto throw off the stitch upon the tuckstitch needles of thenon-fashioning needles, as before described, the upright 19 is lifted bymeans of the frame 28 and connecting-rod 29. The elevation of theupright 19 has no effect upon upright 23, but lifts the arm 20, so thatthe cam-face 21 is in line with the projection 15 of lever 13. and whenin the retation of the machine it is struck by said lever the leverturns, lifting the block 3 and bringing the switch-cam 7 to the highlevel, so as to throw off the stitches upon both the short and the longlatch fashioning-needles. (See Fig. 15.) WVhen the upright 19 descends,due to the downward movement of the frame 28 imparted by theconnecting-rod 29 and the rock-shaft G, the cam-face 21 is brought inline with the projection 18 of lever 16, and when struck by saidprojection the lever 13 is moved to bring the end free from the block 3and the block by the action of its spring descends and the cam 7 isbrought to the low point, so that the long-latch fashioning-nee- IOf IIC

IIC

dles take the thread but do not cast the stitch, while the short-latchedfashioning-needles both take and cast the stitch. (See Fig. 16.) Whenthe clutch-shifting cam 39 is operated to shift the connection of thecam-cylinder from the rotary mechanism to the reciprocating mechanism,(forming the heel or toe,) the arm 41 is lifted, bringing the projection42 against the projection 44, lifting the upright 23 and through it theupright 19, bringing the cam 21 in alinement with the projection 15 oflever 15, thus forcing the cam 7 to its high point, Where all thefashioning-needles will cast the stitches. The movement of the arm 41also moves the vertical projection 43 against the cut-away portion 34 ofcatch 33, holding the catch out. This position is maintained during theentire reciprocation, and thus during this period none of the fashion,-ing-needles form tuck-stitches. When the shift of the cam 39 is made tochange the camcylinder-operating mechanism from reciprocation torotation, the arm 41 descends, releasing the upright 23, which will thendescend and bring the cam 21 in alinement with the projection 18 oflever 16, releasing the block and bringing the cam 7 to its low point.If, however, this last-mentioned shift from reciprocation of thecam-cylinder to rotation be for the formation of the foot, the lug 50 onthe pattern-chain strikes the tailpiece 45, the upright 23 is lifted orheld lifted, and the catch 33 holds it there until the shift is madeagain to and from reciprocation. Thus by this construction thetuck-stitching upon the fashioning-needles during the formation of theleg of the stocking is formed corresponding to that formed upon the nonfashioning needles. Again, where the fashioning-needles are used in theformation of the heel or toe or sole of the foot tuck-stitches areformed upon none of them. The reason for pivoting the arm carrying thecam 21 and making it freely yielding in one direction is that it willyield if for any reason during the reciprocation of the machine itshould be struck.

Having now fully described my invention, what I claim, and desire toprotect by Letters Patent, is
